Definitions

  • the present invention relates to the field of material handling, and more specifically, to a process for handling cargo and a cargo handling facility for use in such process.
  • Containerization pemits substantial improvements in the speed by which cargo is loaded and unloaded, and in the shipping industry, profits are made by maximizing the amount of time that vessels are in production, namely, transporting goods, and minimizing the amount of time that vessels are in port.
  • standard containers are typically engineered for loads up to 20 tons, whereas many discrete loads, such as steel coils, are in excess of that mass.
  • lakers which carry the bulk of the cargo within the Great Lakes, are of a size and configuration which is not amenable to the large scale cartage of containers.
  • the process for handling cargo comprises the step of providing a cargo handling facility.
  • the cargo handling facility includes a wharf defining a marine berth of sufficient length to accommodate the docking of a marine vessel in substantially parallel relation to a sidewall of the wharf; a shelter having a roof structure overlying the marine berth and an adjacent portion of the wharf; one or more overhead lifting means, such as overhead cranes, are mounted beneath the roof structure for movement over the marine berth and over the adjacent portion of the wharf in both transverse and parallel directions relative to the sidewall of the wharf.
  • This provides for movement of the cargo by the overhead lifting means between the marine vessel and one or more exterior transport positions located on the wharf, which exterior transport positions are also preferably located under the roof structure.
  • the cargo handling facility preferably further includes a waterside wall extending upwardly, from the bed of water on which the wharf sits, to the roof structure, so that the marine berth is sheltered on the water side by the waterside wall.
  • the cargo handling facility preferably also further includes a warehouse having an access wall in which one or more cargo doorways opening onto the wharf are provided.
  • the warehouse structure is preferably oriented with its access wall positioned towards and arranged substantially parallel to the waterside edge of the wharf, such that the marine berth is sheltered on the land side by the access wall.
  • the one or more exterior transport positions are preferably located one each on the wharf outside a respective one of the one or more cargo doorways.
  • One or more cargo conveyance means are preferably associated one each with said one or more cargo doorways, and each of said one or more cargo conveyance means is adapted to convey cargo between a respective exterior transport position on the wharf outside its associated cargo doorway to a respective interior transport position in the warehouse inside its associated cargo doorway.
  • the transport means is for moving cargo between the interior transport positions and the interior of the warehouse.
  • the location and the structure of the facility provides for an efficient and advantageous deployment of stevedore and warehouse labour, thereby to permit handling of cargo, including breakbulk cargo, in a manner that is relatively inexpensive as compared to conventional breakbulk cargo handling processes.
  • FIG. 1 is a plan view of a cargo handling facility provided in a preferred embodiment of the process of the present invention

  • the transport means 34 is for moving cargo between the interior transport positions 74 and the interior 79 of the warehouse 24 and, as illustrated in FIG. 11 , in the preferred embodiment comprises, for each cargo conveyance means 28 , a second overhead crane 94 having a pair of rails 96 extending, on opposite sides of said each conveyor 28 , from the access wall 46 , and in substantially normal relation thereto, to the back wall 48 of the warehouse 24 , and provided with two bridges 98 , each having a single trolley hoist 100 rated for 50 tons.
  • a vessel to be unloaded will be maneuvered into the marine berth, as indicated by the sequence of FIG. 3 and FIG. 4 , and secured to the wharf 22 in a conventional manner (not shown).
  • such cargo will be breakbulk cargo, such as coils of steels, stowed in the hold, as well as sundry containers secured topside to the vessel.
  • Unloading involves opening the doors to the hold of the vessel, as indicated by the sequence of FIGS. 5, 6 ; withdrawing a piece of cargo from the hold, as indicated by the sequence of FIGS. 6,7 ; and depositing the cargo on a respective wheeled cart 28 , as shown in FIG. 8 , or on the bed of a transport truck 44 , as shown in FIG. 9 .
  • the choice of transport truck, and among the wheeled carts 28 will be calculated by the stevedores, having regard to the intended destination of the goods using conventional logistics techniques which accordingly are not detailed herein.
  • All three hoists 92 on the first overhead crane 86 will be utilized by the stevedores, to expedite unloading of the vessel, and because the wharf 22 and the marine berth 36 are sheltered and illuminated, unloading can be carried on continuously, night and day, and in inclement weather conditions.
  • the associated cargo doorway 54 is opened, the wheeled carts 78 are urged into the warehouse interior 79 ; and the cargo doorway 54 is closed, as indicated by the sequence of FIG. 11 and FIG. 12 .
  • This limits moisture infiltration into the warehouse interior 79 and thus, minimizes corrosion or other moisture-related spoilage of the cargo, as well as loading on the warehouse HVAC system.
  • Warehousing/logistics of the cargo occurs contemporaneously with unloading.
  • warehouse labour utilizing the associated second overhead cranes 94 empty the wheeled cart 78 and deposit the cargo thereon either onto a delivery vehicle 101 located on the delivery alleys 56 , 58 or 60 , as indicated by the sequence of FIG. 10 and FIG. 12 , or into the warehouse, as indicated by the sequence of FIG. 10 and FIG. 11 .
  • the cargo doorway 54 is reopened, and the wheeled cart 78 is returned to the exterior transport position 72 , to receive further cargo, until such time as the vessel is unloaded.
  • the warehouse interior 79 is illuminated and climate controlled, such that operation can be carried on in darkness and inclement weather, so as not to impede the progress of the stevedores.
  • the three bridges 98 and the associated hoists 100 of the second overhead cranes 96 are utilized simultaneously, to expedite unloading, with the bridge 98 disposed nearest the interior transport positions 74 being deployed largely to move cargo off the wheeled carts 78 a short distance within the warehouse 24 , to speed cycle time, and the second overhead cranes 96 more distant being deployed for more time-consuming warehousing/logistics functions.
  • Transport trucks, rail cars/rail car movers and/or tow motors may also be utilized to move cargo within the warehouse, so as to be within the reach of a given second overhead crane 96 , or to bring said cargo into the airlock 66 , to shed excess moisture prior to warehousing, as desired.
  • the consolidation of equipment combined with the ability to readily operate in darkness, and inclement weather conditions, permits permanent staffing of the facility, both in terms of warehouse workers and stevedores, in a shift work environment, which heretofore has been out of reach.
  • the economies of scale inherent in the process and facility disclosed provide significant advantages in efficiencies and costs, particularly in relation to, for example, operating costs, all to the benefit of shippers, port authorities, warehousers and stevedores.
  • the process provides for an efficient allocation of labour between stevedores and warehouse labour, such that the involvement of stevedores in warehouse/logistic efforts is minimized, and such that the involvement of warehouse/logistics employees in stevedoring functions is minimized, with resultant cost benefits flowing therefrom.
